A black or brown tongue typically is due to the overgrowth of bacteria that normally are present on the tongue. This, too, can be caused by the killing of some bacteria with antibiotics so other bacteria overgrow. But the most common cause of discoloration of the tongue is the overgrowth of a fungus. The most common fungus is called candida. But overgrowth of the candida fungus turns the tongue white. Infection with candida is called candidiasis, and when it happens on the tongue the condition is called thrush.
If the white doesnât disappear with your cold, itâs definitely best to get it checked out by your dentist to figure out how to proceed.

In one condition, strawberry tongue, the tongue actually begins to resemble (you guessed it) a strawberry because of some enlarged, red taste buds.
